Miguel Ferrer's (†61) death in 2017 not only devastated his hundreds of thousands of fans, but also the entire NCIS: L.A. production team and his fellow cast members. Ferrer played Owen Granger from 2012 to 2017. After he was diagnosed with larynx cancer the show's writers changed the screenplay so that he could carry on working in spite of his diagnosis.

According to Hollywood Reporter, the screenplay was changed so that Ferrer did not have as many lines, so that viewers would not notice that his voice was becoming increasingly weaker over time. His character was also diagnosed with cancer and Granger was shown undergoing chemotherapy.
